SHUTTER OPENING AND CLOSING iviECiiANIsMqf Y' To all whom z'tmag/ concern." a

Be it known that l, FRIEDRICH EsA, a citizen of the United States, residing at Fairfield, inthe county ofv Teton and -State of Montana, Vhave invented certain new and useful Improvements in Shutter-Opening and Closing Mechanism, of which the following is a specification.

The invention relates to blind or' *shutter I opening and closing mechanism, and more particularly to the class of combined shutter locks and opening and closing-mechanism therefor.'v 'Y W Y The primary object of the invention is the provision of mechanism off this char# acterzwhereiii the'swinging window shutters or blinds canbe conveniently and readily opi erated'froni wit-hin an-inclosure for the open-` ing and vclosing thereof without' necessi-v tating the raising ofthe saslies of the win` dow as is usual, theblinds jor shutters when" in closed position or in open position beingij llocked to avoid the accidental swinging thereof.

Another object ofthe invention is the pro-f vision of mechanism of this character wherein the same can be mounted Vrelative to theswinging blinds of a window for the suc` cessful-operation thereof to both lock the blinds 'and when released to open or close the saine automatically, thereby eliminating v the manual labor required in swinging the4 blinds to open or closed position, the mounting of the mechanism being of novel form so Y as to avoid anyfnecessity of vchangingfor altering the window construction lor the blinds orshutterstherefor'.

Another object of Ltlieinvention is the provision of mechanism of this character,

wherein the construction thereof isl novel in form so as toassurethe easy and convenient opening or closing of the blinds and `the locking thereof in either position, without necessitating the opening ofthe sashes or.`

the lmanual handling of the blinds in the K f I immediately4 below vthe sills .thereof and ad-v struction, very reliable and eiiicient in operation, readily and' easily applied to a'winf-r dow construction, strong, durable, and in expensive to manufacture andjinstall'. -beveledpinion 13' which isiXeduponthe.

With' these and other'objects in view, the invention consistsnn 'fthe features kof con-1 struction;:combination and Jarrangement of parts aszwill be hereinafter fully described,

lillustrated in the accompanying'drawingsg and pointed out inthe claims hereunto appended. A Y
